Which RAID configuration level provides increased performance using only two disks?

RAID 0 is designed to enhance performance by striping data across multiple disks, which means that data is split into chunks that are written to each disk simultaneously. This paralleling of data writing and reading elevates disk access speeds significantly, resulting in improved performance for applications and tasks that require high throughput.

In a two-disk configuration, RAID 0 maximizes the use of disk space as well, offering a total capacity equal to the combined size of both disks. There is no redundancy in RAID 0, meaning if one disk fails, all data is lost, but that trade-off allows it to deliver excellent performance advantages.

On the other hand, RAID 1 mirrors data between two disks for redundancy, but does not provide a performance increase since the same data is written to both disks. RAID 5 requires a minimum of three disks and provides both redundancy and performance enhancements, but cannot operate with just two disks. RAID 10, which combines striping and mirroring, requires at least four disks and cannot be used with only two disks while still providing redundancy and performance.

Thus, RAID 0 stands out as the RAID level that offers increased performance using exactly two disks.
